Comparative analysis of two different fixations for intertrochanteric fractures

Objective To compare the dynamic hip screw(dynamic hip screw,DHS) and anti-spin proximal femoral intramedullary nail(proximalfemornal nail antirotation,PFNA) internal fixation in the treatment of intertrochanteric fractures.Methods Fifty-six cases intertrochanteric fractures were randomly divided into 28 cases of the PFNA group and DHS group,and the operative time,intraoperative amount of bleeding,healing time and the Harris hip score and complications were observed and compared between the two groups.Results PFNA group had less surgery time,less blood loss,mean fracture healing time was short,compared with the DHS group,the difference was significant between PFNA group and DHS group;the postoperative complication rate of PFNA group was significantly lower than the DHS group,and the difference was significant(P 0.05).PFNA group and DHS group had similar excellent and good rate of hip Haris score,and the difference was not significant(P 0.05).Conclusion PFNA and DHS intreatment of intertrochanteric fractures have good results,but relative to the DHS,surgical time,blood loss,mean fracture healing time of PFNA are less;during and after surgery PFNA has fewer complications,and is more suitable for clinical extensive promotion and application of fixation.
